- Demonic Spiders: Quite fittingly, the spiders. Who will insta-kill you if you're caught without a full set of armor.
- Nightmare Fuel: Naturally, to anyone who has a phobia of insects, specially spiders. The game comes with an accessibility option that allows arachnophobic players to scale back the spideriness of the spiders, to the maximum potential of them looking like floating white blobs.
YMMV / Grounded
